Abstract

This paper reports on the development of general-purpose component-based connection finite element intended to model the performance of steel-to-steel joints in fire. The element is generally consistent with Eurocode principles. The development began with the creation of an assembled component-based finite element to represent the flush endplate connection type, in the main using temperature-dependent connection component characteristics which had previously been developed at the University of Sheffield for behaviour up to very high distortions and ultimate fracture, as well as for force reversal.  In subsequent work, components for the reverse-channel have been characterized and validated against both numerical modelling and high-temperature testing. The element has been incorporated into the nonlinear global structural analysis program Vulcan, developed at the University of Sheffield.
